This paper describes a new finishing process using magnetic abrasiveswere newly made to finish effectively brass plate that is very difficult to be polished by the conventional machining processes.Taguchi experimental design method was adopted for evaluating the effect of the process parameters on the improvement of the surface roughness and hardness by the magnetic abrasive polishing.The process parameters are: the applied current to the inductor, the working gap between the workpiece and the inductor, the rotational speed and the volume of powder. The analysis of variance (ANOVA) wasanalyzed using statistical softwareto identify theoptimal conditions for better surface roughness and hardness. Regressions models based on statistical-mathematical approach by using the MINITAB-statistical software for both surface roughness and hardness were obtained.Experimental results indicated that rotational speed is the most significant parameters on change in surface roughness(ΔRa), and for change in surface hardness (ΔHa), volume of powder is the significant one.As a result, it was seen that the magnetic abrasive polishing was very useful for finishing the brass alloy plate.
